Windows 7: System Freezes & hangs - possible broken motherboard?

My system is completely unstable - it regularly hangs/freezes/stalls/makes horrible noises - this can be at any time: during boot-up, when windows is loading, whilst browsing, playing games - there is no consistent trigger.

Last week my PSU went bang and since then it's been far far worse. (replaced it & updated profile specs).

I've been trying to establish the fault and I've done the following:

- Run chkdsk on both hard disks (windows mounted on 1 disk, my docs etc. on disk 2) with no faults
- Run Memtest86+ for about an hour with no faults found
- Run FurMark for about 5 mins with no stability issues/crashing etc (temp got up to about 97c)

I've been trying to run Hot CPU Lite but it always seems to freeze about an hour into the test (if it gets that far).

I'm thinking that it looks like the motherboard is the problem, and the PSU going may have done some additional damage. Unfortunately I don't have a spare one lying around that I can test it with so wanted some opinions before I go spending money I don't have on something I might not need!

At any rate you are getting a 124 stop which does indicate a hardware level problem. Trying to narrow it down can be a bit of an issue. We have a thread on this kind of failure and a list of things to do to narrow it down. Stop 0x124 - what it means and what to try

Sorry I can only really verify what you already suspected. However you can be confident you have a hardware related problem at this point.

Thanks for confirming my suspicions. Seeing as I've run test on the GPU & RAM (I'll try to run MemTest86+ overnight to give it a really good run) then it's looking like it's the mobo.....the only other piece of hardware I have is a wifi card. I'll remove it, boot up & see if that makes any significant changes.

Shopping for new mobo now. Choice is slightly overwhelming! Looking at either ASUS or Gigabyte. Will buy, install & report back here when all done. Hopefully it'll fix it...if not, I might be sleeping on the sofa for a while :)

System Freezes & hangs - possible broken motherboard?

Sporadic system hangs/freezes, no BSODs or recent major HW/SW changesA bit rambly, I apologize, but there's a TLDR blurb at the end.
*****
A bit under two weeks I got on my computer in the morning and it was acting semi-frozen. I was able to swap between one or two windows before everything stopped responding. Throughout this I had full control of the mouse,...
